When ${S} == ${WORKDIR}, the eclass creates a build dir that is not nested within ${WORKDIR}: >>> Compiling source in /var/tmp/portage/dev-cpp/antlr-cpp-4.11.1/work ... debug: cmake_src_compile: entering function, parameters: debug: cmake_build: entering function, parameters: * Source directory (CMAKE_USE_DIR): "/var/tmp/portage/dev-cpp/antlr-cpp-4.11.1/work" * Build directory (BUILD_DIR): "/var/tmp/portage/dev-cpp/antlr-cpp-4.11.1/work_build" I filed a bug for portage too. Regardless, cmake.eclass should only create directories nested within ${WORKDIR}.

Creating directories above WORKDIR is not legal. Portage has its own bug (bug #889418) in that it doesn't clean up unknown directories above WORKDIR in PORTAGE_TMPDIR, so combined, you get a problem where "ebuild ... clean" doesn't actually clean things up at all, and you get very confusing issues if e.g. changing CC between runs. The explicit S=WORKDIR check isn't truly needed but it makes explicit our intent here.
